Waverly Water Hardness & Quality Report (2026)

Waverly, Michigan, in Eaton County immediately west of Lansing along the Grand River corridor — a growing suburban community sharing the Lansing metro area's water infrastructure — receives its municipal water from the Lansing Board of Water and Light (BWL), Michigan's largest publicly owned combined electric and water utility. BWL draws from the Grand River through intake facilities in the Lansing area, treating the water at the Sparrow Hospital Road Water Treatment Plant before distributing to Lansing and adjacent communities including Eaton County's Waverly area.

The moderately hard 166 mg/L hardness and TDS of 349.8 mg/L reflect the Grand River's consistent carbonate character through central Michigan. The Grand River at Lansing drains a broad watershed that contacts Devonian and Silurian carbonate formations of the Michigan Basin — including the Traverse Group limestone, Niagara Dolomite, and Bass Islands Dolomite — the same formations producing moderately hard water throughout Michigan's lower peninsula. Groundwater baseflow from the carbonate aquifer sustains the Grand River through dry seasons, ensuring that carbonate hardness remains consistent throughout the year in the Lansing BWL supply.

At 166 mg/L, Waverly residents deal with moderately hard water familiar throughout the Lansing metropolitan area. Scale builds gradually in kettles and coffee machines over months, the dishwasher benefits from rinse aid, and bathroom surfaces develop light calcium rings requiring periodic cleaning. Quarterly descaling of heating appliances is the standard schedule for Eaton County households. The elevated PFAS level of 9.4 ppt is the primary drinking water concern for Waverly — the Lansing metro area's PFAS burden from Capital Region International Airport and industrial sources affects the Grand River watershed. A certified reverse osmosis filter for drinking and cooking water is strongly recommended.
